7MS #464: Interview with Christopher Fielder of Arctic Wolf

Today our friend Christopher Fielder of Arctic Wolf joins us on the show again (check out his first appearance in episode #444 - this time to talk about the security journey, and how to start out in your "security diapers" and mature towards a stronger infosec program. Specifically, we talk about:

  • When the company has one person in charge of IT/security, how can you start taking security seriously without burning this person out? First, it's probably a good idea to take note of what you have as far as people, tools and technology to help you meet your security goals.

  • Early in this process, you should inventory what you have (see CIS controls) so you know what you need to protect. A few tools to help you get started:

  • As you go about any phase of your security journey, don't ever think "I'm good, I'm secure!"

  • Quarterly/yearly vulnerability scans just won't cut it in today's threat landscape - especially your external network. Consider scanning it nightly to catch show-stoppers like Hafnium early)

  • Limiting administrative privileges is SUPER important - but don't take our word for it, check out this report from Beyond Trust for some important stats like "...enforcing least privilege and removing admin rights eliminates 56% of critical Microsoft vulnerabilities."

  • Install LAPS, because if an attacker gets local admin access everywhere, that's in many ways just as good as Domain Admin!

  • Train your users on relevant security topics. Then train them again. Then....again. And after that? Again.

  • There are many ways to conduct tabletop exercises. They don't have to be crazy technical. Start with the internal tech teams, practice some scenarios and get everybody loosened up. Then add the executives to those meetings so that everybody is more at ease.

  • How do you know when it's time to ask for help from an outside security resource?

  • Not sure what kind of shape your company's security posture is in? Check out Arctic Wolf's free security maturity assessment.

7MS #147: DIY Hosted Mutillidae

In this episode I talk about how to build a cheap hosted Mutillidae server to safely hack away on while keeping other Internet prowlers out. Here are the basic commands to run to lock down the Digital Ocean droplet's iptables firewall: *Flush existing rules* **sudo iptables -F** *Allow all concurrent connections* **sudo iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT** *Allow specific IPs/hosts to access port 80* **sudo iptables -A INPUT -p tcp -s F.Q.D.N --dport 80 -m conntrack --ctstate NEW,ESTABLISHED -j ACCEPT** *Allow specific IPs/hosts to access port 22* **sudo iptables -A INPUT -p tcp -s F.Q.D.N --dport 22 -m conntrack --ctstate NEW,ESTABLISHED -j ACCEPT** *Block all other traffic:* **sudo iptables -P INPUT DROP** *Provide the VPS loopback access:* **sudo iptables -I INPUT 1 -i lo -j ACCEPT** *Install iptables-persistent to ensure rules survive a reboot:* **sudo apt-get install iptables-persistent** *Start iptables-persistent service* **sudo service iptables-persistent start** *If you make iptables changes after this and they don't seem to stick, do this:* **sudo iptables-save > /etc/iptables/rules.v4** See this Digital Ocean article for more information.
